With a majority of students now having access to smartphones, there are growing opportunities to leverage this technology for student labs, particularly in conjunction with online coursework. There is also a small but growing market of add-on devices that increase the data collection capabilities of these devices. We present a cheap and easy to assemble DIY spectrometer designed for smartphone cameras. The hardware design is open-source as is the accompanying analysis software -- meaning that students can access this technology very cheaply on their own. We will share our experience in utilizing this technology for student labs in our online Introductory Astronomy course at Gadsden State Community College.
